\ BOTTLE.

SPECIFICATION forming part of Letters Patent No. 302,565, dated July 29, 1884.

Application filed October 8, 1883. (No model.)

To aZZ whom; it may concern.-

Be it known that I, Lnwrs STEBBINS HOYT, a citizen of the United States, residing at Boston, in the county of Sufiolk and State ofMassachuset-ts,have invented an Improvement in Bottles Designed to Contain Aerated or Garbonated Liquid Beverages, of which the following is aspecification.

The object of my invention is to produce a IO bottle or vessel which may, by automaticallyarranged valves and constructed openings in p the bottom of the same, be charged with effervescing liquid compounds, while the mouth or ordinary orifice of the bottle orvessel remains 1 5 hermetically closed with my improved patent stopple, or in any sealed. I l

Myinvention consists in a bottle or vessel,

preferably of glass, and similar in general outline to bottles at present used, but having a concaved depression in the under side of the bottom,with-an outwardly and centrally projecting short neck screw-threaded at its outer circumference, through which is a smaller orifice for the admission of the filling-tube conveying the liquid compounds into the bottle.

A self-closing combined valve and packing,of

rubber or any suitable material conforming'to the circular shape of said projecting neck, is

placed upon the latter in a position which admits thevalve to open inwardly when acted upon or displaced by the downward pressure of the filling-tube. Said packing and valve is protected and confined by a strong cap of 3 5 metal, glass,'or other suitable material, threaded interiorly and fitting the projecting neck,

over which it is placed and held by the corre sponding thread around the same. The top of this threaded'cap has a central opening for 40 theinsertion of the filling-tube, which opening is. closed on the withdrawalof said tube by a suitably-molded projection on the outer surface of the valve-flap, the effective action of said valve being further secured through the pressure of the surcharged liquids within the bottle. y

A more explicit description of my invention is embodied in the drawings and in the description thereof, wherein-- Figure 1 represents an elevation, in part seeother manner corked or 7 tion, of a bottle embodying my improvement in its construction. Fig. 2 combines a side elevation and an under plan view of the rub ber valve. Fig. 3 is a transverse section through line as, Fig. 1. of the bottle-bottom sealed. Fig. 5 is alongitudinal section of the lower part of my'improved bottlein position and process of filling.

Referring to the letters, Ais the bottle,hermetically closed at its top, the lower portion ofrwhieh at B is so constructed as to form a suitable depression of sufficient depth to. insure non-contact of the valve-cover or its parts when the bottle is in an upright position,as at Fig. 1.

0 indicates the line of the bottom,which is pierced at D with an opening for the admission of the carbonated liquid. Said opening is in formlike a cone, the walls diverging from the exterior to afford space for the valve or flap G, forming a part of the washer E, allowing said flap to rest against the side of the orifice when pushed there by the insertion of the filling-tube K, as exhibited in Fig. 5. The washerv and valve is preferably formed in one piece, in shape circulalgand in diameter sufiicient to cover the surface'of the threaded proj ection forming its seat. The central portion or flap, G, forming the valve,is cut semicircular with its hinge at h, and of proper circumfer- 8o ence to close the smaller diameter of the aperture D, and has upon its outside floor a projecting nipple or plug, 9, as in Fig. 2. Said plug is for the purpose of forming an auxiliary valve to close the tube-aperture H in the screw-cap I, which. is threaded internally to fit the corresponding thread around the projecting neck J of the bottle -bottom 0, the screw-cap I confining the valve and washer in position. The aperture H receives the plug 9. 0 which is forced, by the pressure of the liquid contents, so as to proj ect through and expand,

as at n, Fig. 1, beyond the outer circular edge of said opening H, forming a secure filling to the same. The edges both of valve and plug are cut at an angle, as at 1; 4 Fig. 2, conforming to the angle of the walls of the openings in the bottom and screw-cap, so as to form acloser and firmer connection with the adjacent parts.

Fig. 4 shows a plan 55 f IOO In the process of filling, the bottle or vessel is inverted, and in this position is held and n1ovedby the ordinary appliances for bottling under the filling-tube. The latter is 5 then moved downward, the mouth of said tube coming in contact with the projecting plug g, which presses the plug and valve G inwardly and against the wall or side of the conical opening D,when the liquid is injected through the tube and the bottle filled,as in Fig. 5. The filling-tube then being withdrawn, the pressure of the gas forming a component part of the liquid is exerted against the inner floor of the valve and restores it to its normal position, I 5 hermetically closing the bottle. To provide for the displacement and escape of air from within the bottle while injecting the contents, the filling-tubes are usually provided with longitudinal grooves upon their outer surface, 20 or they may be of corrugated form.

Having described the construction and operation of my invention,what I claim is 1. An imp roved bottle,,as is herein described, having the depression B, the bottom 0, pro- 2 5 vided with the conical smooth-surfaced open ing D, the projecting threaded neck, the automatic valve E, having the plug 9, with inclined walls, and sealing-cap I, having a conical orifice, H, all as and for the purpose set forth.

2. In combination with a bottle having a perforated bottom, 0, the valve and packing E, having the projecting plug g, with inclined wallsii, and cap I,having the conical orifice H, as and for the purpose specified.

3. In animprovedbottle, thcthreaded conically-pefforated screw-cap I, in combination with thevalve E, having plug 9, with inclined walls *6 t, and bottle-bottom G, threaded and perforated, as herein set forth.

4. As an article of manufacture a bottle having a comically-perforated bottom and a hermetically self closing valve, constructed and operating as herein described, and specially constructed to contain aerated liquids, as specified.

In testimony whereof I have signed thi specification in presence of two subscribing witnesses.
